Lm385z Datasheet Marvelous Lm385z 1 2 Datasheet Pdf On Semiconductor

You must select a value well below this. The circuit operates as a resistive voltage divider.

When the voltage is less than 5V they can be neglected. Select a lower value for R1. Sign up using Email and Password. AltAir 2 To achieve the desired result descending resistance R1. Those references are not batteries.

As if they are not. Then the curtain will rise. And it is so, if R2 and R3 are not present in the circuit.

Enric Blanco 4, 5 11 I changed R2 and R3 to 47k and 22k and all works fine!

That adds up to a minimum of 0. Em Ka 48 7. Tony EE rocketscientist 62k 2 21 If you don’t feed them with dataaheet current and voltage they are just resistors. Just think about it a while and calculate what the voltage at that junction is with D2 and D3 removed.

Email Required, but never shown. Add that to your 5Volts, and you have Besides, from what I understand voltage across anode of D1 and cathode of D2 should be always 5V, right? The problem you’re encountering is that R1 is so high that it doesn’t let enough current flowing through to operate the diodes as they should.

D2 and D3 cannot magically make 5 volts appear at the junction of R1 and R2 if the basic voltage at the point is less than 5 volt when D2 and D3 are not present. The diodes need, according to the datasheet, a minimum of 20 uA to operate. daatsheet

However, at 4V voltage drop, the 10k resistor can only provide 0. Andy aka k 10 I’m doing a simple circuit using LM Sign up using Facebook. You can’t do this dxtasheet one 9V battery.

You need to drop the 10K to a lower value, or use two batteries, but make sure you don’t exceed the maximum bias currents for your references. However when I measure it, OUT is only 2. I don’t understand what you mean by resistive voltage divider – could you please explain?

Em Ka, D2 and D3 ‘start working’ when the voltage is higher to 5V in.
